Sewing machine and non-transitory computer-readable medium

摘要

The sewing machine includes a needle bar, a needle bar mechanism, a moving mechanism, a projector, a processor, and a memory. The memory is configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising specifying, a plurality of times, a position of an ultrasonic wave transmission source on a workpiece based on ultrasonic waves, setting a first stitch pattern and a sewing position of the first stitch pattern, based on a plurality of specified positions, causing the projector to project an image that shows the first stitch pattern onto the workpiece in the sewing position, creating first stitch pattern data for sewing the first stitch pattern in the sewing position, and causing, based on the first stitch pattern data, the moving mechanism to move the workpiece and the needle bar mechanism to move the needle up and down.

主权项

1. A sewing machine comprising:
a needle bar configured to be mounted with a sewing needle; a needle bar mechanism configured to move the needle bar up and down; a moving mechanism configured to move a workpiece to be sewn; a projector; an ultrasonic wave transmission source; an ultrasonic wave detection device; a processor; and a memory configured to store computer-readable instructions that, when executed by the processor, instruct the processor to perform processes comprising: specifying, a plurality of times, a position of the ultrasonic wave transmission source on the workpiece, based on ultrasonic waves detected by the ultrasonic wave detection device, setting a first stitch pattern and a sewing position of the first stitch pattern on the workpiece, based on a plurality of specified positions of the ultrasonic wave transmission source acquired by the specifying of the position the plurality of times, the first stitch pattern being a stitch pattern, causing the projector to project an image that shows the first stitch pattern onto the workpiece in the sewing position, creating first stitch pattern data for sewing the first stitch pattern in the sewing position, based on at least the first stitch pattern and the sewing position, and causing, based on the created first stitch pattern data, the moving mechanism to move the workpiece and the needle bar mechanism to move the needle bar up and down.
